Infra: simplify bot-server installation config (#11144)

- Simplify, inline run configuration directly into systemctl file.
- Rename bot variables:
   - 'bot_name' -> 'bot_location_city_name'
   - 'bot_prefix' -> 'bot_number'
- Reload systemctl file automatically when starting
- Conditionally reload systemctl on deployment only when systemctl
  file has changed.
